What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Hypothesis: Proximal humerus fractures present a treatment challenge due to varied fracture configurations and a lack of consensus on optimal management. Locking plate designs offer promising solutions, yet technical guidelines for successful outcomes remain elusive. Complications are common, with fixation-related failures often attributed to varus collapse. Addressing this, we review a novel intraoperative technique of medialization of the humerus shaft to provide medial buttress support to the humerus head. Methods: This retrospective study included acute 3-part and 4-part proximal humerus fractures treated with open reduction and proximal humerus locking plate fixation from February 2013 to August 2021, which were restored by creating medial buttress by the described technique. Central Column Diaphyseal angle was measured on the 20° external rotation anteroposterior X-ray radiograph, by measuring the intersection angle of the axis of the proximal part of the humerus and the line perpendicular to the anatomical neck. The functional outcome was measured with the Constant score that assesses pain and shoulder function during daily activities, range of motion, and shoulder strength at each follow-up. Results: Seventy-six patients with acute 3- and 4-part proximal humerus fractures were treated using this technique and followed for an average of 16 months. Results showed successful union in 76% of cases within 12 weeks, with no nonunions or implant failures requiring revision surgery at a minimum of 24 months follow-up. Functional outcomes were favorable in 70% of patients. However, avascular necrosis of the humeral head occurred in 12% of cases. Conclusion: Despite limitations, this technique offers a biomechanically sound approach to enhance fixation stability, potentially improving the outcomes in proximal humerus fractures without the need for any additional fibular grafting procedures.
